Images Stopped Scrolling

Can someone please tell me why my images have stopped scrolling on my homepage? I cant see any errors in the HTML and not sure what is causing this. Any help would be greatly appreciated.

<div id="mygallery" class="alignright"><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/1.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/2.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/3.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/4.jpg" alt="" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/5.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/6.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/7.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/8.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/9.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/10.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/11.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/12.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/13.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/14.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/15.jpg" alt="Street Teams" /><img src="http://70.32.110.35/wp-content/uploads/2009/09/photo/16.jpg" alt="Street Teams" /></div>
